I've got some pictures of the old 219 Drive-In Theater that was located just south of Deep Creek Lake, Maryland on Rt. 219 across from the Sand Flat Road intersection. The coordinates are: N39 29.027, W079 21.023.
I scanned a picture of the old Drive-In itself, and a picture of the sign showing what was playing on Friday September 2, 1963. Am I good or what?!!! They were in an advertisement in our old high school yearbook. That flat roofed building in the middle of the parking lot housed the projection booth and the concession stand.
The parking lot is now the 219 Outdoor (Garden) Center. All the poles that held the speakers are long gone, but the screen is still standing, and the concession building now has a second floor and serves as a store for the garden center.
I can still smell the popcorn... thanks for the trip down memory lane! tmp
